Thanks to its internal architecture, it can work with any mail client (Outlook, Thunderbird, Eudora, Pegasus and anything that supports the POP3 protocol). All you need to do is install it and reconfigure your mail client to use ClamMail as a POP3 proxy: - change your pop3 server to localhost - change your username from "foo" to "foo\mail.myserver.com" where mail.myserver.com is your real pop3 server.
